print the code which defined a lambda function<>
This question already has an answer here:
As long as you save your code to a source file you can retrieve the source code of an object using the inspect module.
example: open editor type:
myfunction = lambda x: x==2
save as lamtest.py
open shell type python to get to interactive python type the following:
>>>from lamtest import myfunc >>>import inspect >>>inspect.getsource(myfunc)
'myfunc = lambda x: x==2\n'
